Question

我正在尝试使用SpringJUnit4ClassRunner创建单元测试，但每次执行测试时它都说使用mvn install找不到SpringJUnit4ClassRunner。

\src\test\java\com\jr\freedom\util\JsonParserUtilTest.java:11: cannot find symbol
[ERROR] symbol: class SpringJUnit4ClassRunner
[ERROR] -> [Help 1]

这是我的代码

@RunWith(SpringJUnit4ClassRunner.class)
public class JsonParserUtilTest {

    private String jsonUser = "{ \"username\":\"jono111\",\"emailAddress\":\"jon@google.com\", \"password\":\"12345678\",\"firstName\":\"jono\", \"surname\":\"richy\", \"country\":\"united kingdom\",\"bio\":\"Bio stuff goes here about the user. where he comes from etc etc. all is well. lets go go go\" }";

    @Test
    public void testToJsonObject() {

        User user = new User();
        user.setBio("bio mate");
        user.setCountry("uk");
        user.setEmailAddress("jonney@hello.com");
        user.setFirstName("jono");
        user.setPassword("passwordfdsadsa");
        user.setUsername("crazy8");
        JSONObject jsonUser =  JsonPojo.toJsonObject(user);
        assertNotNull(jsonUser);
        assertNotNull(jsonUser.keys());
        System.out.println(jsonUser);

    }

    @Test
    public void testToObject(){
        JSONObject jsonUser = JSONObject.fromObject(jsonUser);
    }

这是我的POM文件：

我正在使用springSource工具套装IDE来开发这个spring mvc应用程序，在IDE上它突出显示SpringJUnit4ClassRunner是一个错误，说它无法解决，尽管我在我的pom文件中包含了所有必要的依赖项。

由于

Answer 1

我下载了您的代码并让它在本地工作，只要我包含相关的导入语句：

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.junit.runner.RunWith;
import org.junit.Test;
...

也许你错过了某处的导入。

Answer 2

我通过

解决了这个问题

删除我的本地maven repo（〜/ .m2 / repository）和
在eclipse中强制执行新版本（Project-＆gt; Clean ...）

Sourced from the appfuse forums

Answer 3

仅供参考，请在您的pom.xml中添加

 <dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-test</artifactId>
  <scope>test</scope>
</dependency>

Answer 4

如果您使用的是Linux，请打开termial并执行以下命令。不要忘记在“用户名”

的位置添加用户

cd /home/you-user/.m2/repository/ sudo rm -r junit

Answer 5

可能是您丢了包裹

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-test</artifactId>
  <version>5.1.7.RELEASE</version>
</dependency>

Answer 6

我不得不将sprint-test jar放在Java Build Path的“ TOP”中

Answer 7

转到pom.xml并确保您的文件包含此依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.1.7.RELEASE</version>
</dependency>

还要确保在此依赖项中没有“作用域”节点：

<scope>test</scope>

找不到SpringJUnit4ClassRunner类
